So i realized that Borla came out with a touring cat back exhaust for the Si.
After seeing the R&D video i was confused because I saw a resonator behind the tip.
After contacting Borla that the system is only single muffler (as below).

I'm curious to know what it would sound like does anyone have an idea?
Its 2.5in - i'm thinking with a RV6 catless DP it would sound nice and allow usable torque to stay around 2500 rpm for daily driving. And of course a tune
Any ideas??
